identify 3 properties of water and include a description of how these properties sustain life
Homework Answers
1) Cohesion, otherwise known as water's attraction to other water molecules, is one of the major properties of water. Water's polarity lends it to be attracted to other water molecules. The hydrogen bonds in water hold other water molecules together. Due to water's cohesiveness.
2) Water's attraction between molecules of a different substance is called adhesion. Water is adhesive to any molecule it can form hydrogen bonds with. Due to water's adhesiveness.
3) Water is a polar molecule that has a high level of polarity and attraction to ions and other polar molecules.
Life on this planet is based on the chemistry of things in water. Water dissolves many salts making ions available to be used by teams of proteins. Proteins would not be able to take the shape they need to work without interacting with water. DNA and RNA would not work without being in a solution of water. Cell walls could not form without the presence of water.Our body needs water to run most of its functions.
